'II'ROLLEY.

SPECIFICATION forming part of Letters Patent No. 588,488, dated August 17, 1897.

Application filed March 11, 1897.

To all whom it may concern: 7

Be it known that I, GEORGE W. SELL, J r., of J ohnstown, in the county of Oambria and State of Pennsylvania, have invented certain new and useful Improvements inTrolleys; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part of this specification.

This invention relates to trolleys; and the object is to provide an improved trolley-wheel adapted to oscillate as well as rotate on its axis, whereby it automatically conforms itself to the overhead wire or conductor and thereby more readily adapts itself to the varied positions of the latter with relation to the car. A- further object is to provide a trolleywheel support or carrier of improved form.

With these and other objects in view, as will be more fully stated hereinafter, the invention consists in the novel features of construction presently to be described and claimed, and illustrated by the accompanying drawings, in which- V Figure l is a side elevation of the trolley and its support. Fig. 2 is a side elevation of the trolley. Fig. 3 is a cross-sectional view Fig. 4 is an end view. Fig. 5 is a detail view of one of the removable bearing-cups. v

A designates the main post of the support, having its lower end reduced, as at B,'to enter a suitable bearing (not shown) of the cartop structure. Pivoted to the post are the parallel'arms G, which may be of bar metal or pipe, and the same are held in a normally upwardly-inclined position by heavy spring D, secured at its inner end to post A, between the ends of arms 0, and at its outer end secured to lower arm G. Link E connects the outer ends of the arms. Secured to said link is yoke F, and fixed transversely therein is axle Gr, carrying the integral ball H, which constitutes the bearing for trolley I. The

'latter is grooved upon its exterior, as usual,

and upon its inner periphery is formed with the central radial flange J.

K represents two bearing-cups hollowed at their inner ends,' as at L,.to embrace opposite surfaces of ball-bearing H, and-at their Serial No. 627,017. (No model.)

outer ends slotted at M to embrace flange J, to which they are secured by bolts N.

In mounting the trolley one of cups K is first secured in place. The integral ball and axle are then put in place, and then the other cup is inserted and secured. The opposite sides of cups K are countersunk, as shown at O, to receive the bolt-heads and nuts, so that the latter do not protrude beyond the surfaces of the cups. The wheel or trolley thus mounted is most free to rotate and also to oscillate to either side to accommodate itself to the conductor. The support is simple, strong, and most effectual in keeping the trolley to position. I

The wheel-mounting is here shown and described in connection with trolleys only, but I desire it understood that I do not limit myself to its use in this connection, as it may be used to advantage in many and varied arts without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An improved wheel-mounting, consisting of a globular bearing, a wheel, and cups carried by the wheel and adapted to embrace the. bearing, substantially as shown and de-.

scribed.

2. An improved wheel-mounting, consisting of a globular bearing, a wheel, and cups removably secured to the wheel and adapted to embrace the bearing,substantially as shown and described.

3. An improved wheel-mounting,consisting of a globular bearing, a wheel, and oppositely-arranged cups carried by the wheel and adapted toembrace opposite surfaces of the bearing,substantially as shown and described.

4:. An improved trolley, comprising a circular bearing, a Wheel, and cups carried by the wheel and rotatably mounted on the bearing, substantially as shown and described.

5. The combination of'the fixed globular bearing, the wheel formed wit-h the internal flange, and the inwardly extending cups adapted to embrace opposite surfaces of the bearing and slotted at their outer ends to embrace the wheel-fiange to which they are secured, substantially as shown and described.

6. An improved trolley-support, comprising a revoluble upright, two arms pivotally secured thereto-one above the otherand adapted to swing vertically, a spring connecting one of the arms and the support and serving to hold the arms normally in outwardlyextended position, and a trolley at the outer ends of the arms, substantially as shown and described.

7. An improved trolley-support, comprising a revoluble upright, a trolley, a pivoted Vertically-swinging connection uniting the trolley and support, and a contractible spring secured at one end to the connection and at its opposite end to the support above the pivotal point of the connection, whereby said connection is held normally raised in 1aterallyextended position with the trolley in proper adjustment for engaging a conductor, substantially as shown and described.

In testimony whereof I afiix my signature in presence of two witnesses.
